SUBMLARINE" Application filed May 4,

This invention relates to submarines, the.

general object of the invention being to provide movable and stationary wings whereby the ship can be submerged without the use 5 of ballast tanks and to provide two pairsv of propellers which extend in a diagonal direction from the bottom of the boat with means fordi'iving either or both pairs as desired. A further object of the invention is to 10 provide windows in the front of the boat with lamps arranged adjacent some of the windows whereby the water in front of the boat will be illuminatedand a person looking from one ofthe other windows canread- '15 il'y observe what iszahead of him.

A further object of the invention isto' cutting fins at the exterior of the.

provide boat and to provide meansfor circulating the air in the interior thereof. j y

This invention also. consists in certain "other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illus trated in the accompanying drawings and at specifically pointed out in the appended claims. p

In describing my invention in detail reference will be had to the accompanying drawings wherein likecharacters denote like 39 or corresponding parts throughout theseveral views,and in which Figure 1 is a side View of the submarine. Figure 2 is a top plan View. 7 V Figure 3 is a vertical longitudinal see- Figure 4 isa section on line H of Fig ure 3.

Figure 5 is a section on line 5+5 of Fig- 49 Figure 6 is a section on line 6-6 of Fig-- ure 3.

In these views the numeral 1 indicates the body of the boat which is of substantially cigar-shape. A pair of small windows'2 4 are arrangedin the nose of the body adja- 1929. Serial. No; 360,533;

windows 3 are arranged in the body an ap or EAST- sr. LOUiS, ILLINOIS, ASSIGNOROF ONE-HALF TO CALL FORNIA Simon, 01* EAST ST. LOUIS, ILLINOIS I preciable distance from the Windows.

Lamps are located adjacent thewindows. 2 so that the rays of light. therefrom will be projected through the Windows. to the front of the boat, thus enabling the occupants to see objects in front of the boat. A plurality of strips 4, forming fins, are arranged ex teriorly of the boat and extend from the nose thereof tov the rear. The upper and lower fins are toothed as shown and the rear portions are spaced from the body. and are. supported from the. body by the braces. 5.; A depending wing 6 is connected withthe rear end of the top fin and acts to keepthe' submarine from moving from one side to the other. By providing the finswith teeth they will act to cut torpedo nets and other 7 objects in the path of the submarine as well as to turn aside torpedos and damage other boats. The side'fins are spaced from the body but have-their rear ends-connected with the rear of the body and while these fins are shown without teeth they may be provided with teeth if necessary. 'Of course, itwill beunderstood that as many of these. fins may be used-as will be found necessary.

A vertically arranged rudder 7 is pivot ally arranged .at the rear end of the body having its forked inner end fastened to the vertical shaft S which passes through the rear of the body. This shaft has a sprocket 9 thereon over which passes thechainlO the ends of the chain being connectedwith a yoke 11 pivoted in the body and a cable 12 connects one end of the yokewith the lower end of a lever 13 so. that by manipulating this lever the yoke will be rocked to cause the chain to ro k the shaft 8 andthus move the rudder to steer the submarine. j

A pair of wings .14. is pivot lly connected with the front end of the body through means of a shaft 15 which passes horizontally an transverse y through. the front part of the body and has a wing 14 connected with each end thereof. These Wings 14 are arranged in spaces formed by the side fins 4 as clearly shown in Figure 2. A worm gear 16 is connected with the shaft 15 and is engaged by a worm 17 on a shaft 18 which has a hand wheel 19 thereon so that turning this shaft will cause the shaft 15 to rock and thus operate the wings 14 to cause the submarine to submerge or come to the surface. Front and rear pairs of stationary wings are fastened to the body and act to steady the same as well as to help the movable Wings to submerge or emerge the boat.

Front and rear pairs of propellers 21 are used for propelling the boat, the shafts of these propellers extending downwardly and rearwardly from the bottom of the boat.

The shafts pass through the combined bearing and gland members 22, which project from the bottom of the boat and the inner end of each shaft has a pinion 23 thereon. The pinions on each pair of propeller shafts are adapted to engage a large gear 24 slidably arranged on a diagonal shaft 25, suitably supported in the body and 'a spring 26 normally holds each large gear out of mesh with the pinions 23 and also out of mesh with a pinion 27 on a line shaft 28 which is connected by the gears 29 with the shaft of the motor 30. Each large'gear is formed with a groove in its hub to receive the fork ed end of a plate 31 which is guided for bodily movement by the pins 32 carried by one of the supporting members 33 of each diagonal shaft 25. A tilting plate 34 has its trunnions engaging holes in a yoke member 35, this plate being arranged. between the member 33 and the plate 31 whereby .by tilting the plate 34 upwardly the plate 31 is also moved upwardly to cause the gear 24 to move into mesh with both of its pinions 23 and the pinion 27 on the line shaft. When this occurs the shafts of the propellers having their pinions engaging the gear 24 which has been raised will be rotated from the line shaft which is driven from the motor. A pair of levers 36 are arranged adjacent the lever 31 and one of these levers 36 is attached by a link 37 to an arm 38 on one of the tilting plates 34 and the other lever is connected in a like manner with an arm on the other tilting plate. Thus by manipulating these levers 36 either pair of the propellers can be brought into operation or both pairs.

Partitions 39 divide the interior of the body into a compartment 40 and a compartment 41. The machinery is arranged in the compartment 41 while seats 42 are arranged in the compartment 40 for the occupants. The operating levers and the shaft 18 extend into the compartment 40 so that the movements of the boat can be controlled from this compartment.

A fan casing 43 is arranged in the rear part of the body with the fan thereof connected with the rear end of the line shaft. The inlet of the casing is connected with the rear end of the compartment 40 by one or more ducts 44 and pipes 45 lead the air from the exhaust of the casing into the front part of the compartment 40 so that the air in the compartment 40 will be caused to circulate and thus stay pure for a long time.

From the foregoing it will be seen that I have provided simple and efficient means for controlling the movements of a submarine whereby the submarine can be readily steered on the surface or below the surface and can submerge and emerge without the use of ballast tanks.

It is thought from the foregoing description that the advantages and novel features of my invention will be readily apparent.

It is to be understood that I may make changes in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claims.

What I claim is 2- 1. In a submarine, a hollow elliptical body, a motor, a shaft extending longitudinally within the body and driven by the motor, tubular bearing members mounted in the bottom of the body in in shafts, a pinion upon the upper end of each of said shafts, a shaft mounted in advance of each of the propeller shafts with its axis at right angles to the axis of the respective propeller shaft, a crown gear splined upon each of the last mentioned shafts meshing with the respective one of said pinions, pinions upon the first mentioned shaft to mesh each with a respective one of the crown gears, each crown gear having a hub, a bearing plate engaging the hub of each crown gear and tiltable to effect movement of the respective crown gear into engagement with the respective pinions, and means operable to tilt the said bearing plates.

2. In a submarine, a hollow elliptical body, a motor, a shaft extending longitudinally within the body and driven by the motor, tubular bearing members mounted in the bottom of the body in inclined position and one in advance of another, a shaft journalled in each bearing member and extending below the same, a propeller upon the lower end of each of said shafts, a pinion upon the upper end of each of said shafts, a shaft mounted in advance of each of the propeller shafts with its axis propeller shaft, a crown gear splined upon each of the last mentioned shafts meshing with the respective one of said pinions, pinions upon the first mentioned shaft to mesh each with a respective one of the crown gears, each crown gear having a hub, a bearing plate engaging the hub of each crown gear and tiltable to effect movement of the respective crown gear into engagement with the respective pinions, means operable to tilt the said bearing plates, and means yieldably, normally holding each crown gear out of engagement with the respective pinions.

In testimony whereof I afiix my signature.
